Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority to India Provisional Patent Application No. 202011002282, filed Jan. 19, 2020, entitled augmented personnel locator system, and naming Christopher Yates, Laveen Vikram Sundararaj, and Balaramakrishna Rachumallu as inventors, which is incorporated herein by reference in its entirety.

BACKGROUND

A Personnel Locator System (PLS) has limited application for locating personnel on ground using a personal survival radio such as Army Navy/Portable Radio Communications (AN/PRC-112). For example, personnel may carry a hand held personal survival radio that transmits its current location coordinates, while an aircraft PLS communicates (e.g., via an avionics receiver card) with the personal survival radio to receive the location coordinates. The receiver card may then send the coordinates to a Common Avionics Architecture System (CAAS) Flight Manager (FM). The FM application may resolve the coordinates and feed the position info to the CAAS display via Network Data Object (NDO) carried by Ethernet. The Multi-function Display (MFD) hosting Primary Flight Information and Horizontal Situation Indicator (HSI) may have provision to lay the position info on the HSI compass rose.

It may be desirable for the PLS to be augmented to enhance the mission capabilities as well as to assist the pilot with better guidance and information.

An augmented personnel locator system is disclosed for enhancing mission capabilities as well as assisting a pilot with beneficial guidance and information. The augmented personnel locator system is often referred to herein as the Augmented Personnel Locator System (APLS). The APLS may be configured to:

• • 1. Enhance the Range of the PLS by working as a mesh over an existing Survival Radio network (e.g., AN/PRC-112);
  • 2. Receive data from versatile radio (not AN/PRC-112) based mesh networks that can use a standard Interface;
  • 3. Process and display more information from nodes than just personnel location;
  • 4. Algorithmically create new way points based on the information received from nodes; and
  • 5. Assist a pilot in a locator based mission by an exclusive cockpit display overlay.

In embodiments, these capabilities may be realized as follows:

• • 1. Survival radio (e.g., AN/PRC-112) may be configured to operate in a Mesh (topology). This can be attempted by modifying the Software-Defined Radio (SDR) or by adding memory/software that can store and forward. The standard or modified AN/PRC-112 data packet may be used where necessary and where applicable.
  • 2. To have a versatile Radio receiver in parallel to the Survival Radio (e.g., AN/PRC-112) receiver that may receive Data from non-Survival radio based Mesh. One of the parallel data paths may be active based on the Network in use (non AN/PRC-112 networks, e.g., IEEE 802.15.4 based Mesh may also be deployed). The non AN/PRC-112 Versatile receiver can link with a non AN/PRC-112 based Mesh.
  • 3. Survival Radio (e.g., AN/PRC-112) based nodes with interfaces configured to take sensor/data inputs so as to provide information other than just location (e.g., status, health, environment, hazards, and the like).
  • 4. A Mesh of non AN/PRC-112 nodes with versatile interface may also be utilized to take in a variety of Data. These nodes may be carried by humans or piggy-backed to other objects (living or non-living) of interest.
  • 5. Such a variety of Data may have the key information to be used by algorithms for suggesting the path of the flight to carry-out the mission.
  • 6. A dedicated graphic overlay on Cockpit Display can be used as Human Machine Interface (HMI) for selecting, deselecting, choosing the various options that aid the Pilot to enhance safety, mission effectiveness and reduce work-load in Search & Rescue (SAR).

Referring to FIG. 1, the Mesh (based on personal survival radios, such as AN/PRC-112 or Versatile radios) may include: Identifier Nodes 10; Intermediate nodes 20; Receiver nodes 30; and Standard Data packet on the Mesh. In embodiments, an Identifier Node carries location sensor, such as Global Positioning System (GPS) receiver. The Identifier Node may include a Radio Frequency (RF) unit that can communicate via Mobile Ad-hoc Network (MANET) by forming a data link with Mesh topology. A battery is preferably utilized to power the entire set-up. This node could be re-usable or expendable. The Intermediate Nodes may simply include an RF unit with a battery to enhance the range of the Mesh. The Identifier Nodes themselves may also be configured to act as repeaters (Intermediate Nodes) by relaying information of other Identifier nodes when not transmitting their own coordinates. The Receiver Node usually is the sink of the Mesh that receives all the data transmitted over the Mesh. The Receiver Node may be onboard the Aircraft/Watercraft. In embodiments, the Receiver Node includes a software application that can feed the coordinates to the FM unit to resolve the coordinates further to be fed to CAAS Displays or could directly interface with the Displays depending on the Architecture.

The Identifier Nodes may vary in size and range depending on their application. While an Identifier node on a Cargo pallet may be bigger and more powerful, that on a canine scout may be smaller. The Mesh may operate at a predetermined frequency range that may be fixed or hopping. While a sub-gigahertz frequency would give a longer range, it would also require a bigger antenna as well. The Mesh may have a standard Data packet that will be generated, transmitted, routed, received and finally discarded on reaching the intended Receiver node. The Data packets can be encrypted for security so that any intruder cannot decrypt the message fast enough. The Data packets can be transmitted/relayed in response to pre-determined query beacon if the Mesh were to maintain certain levels of Radio silence and stealth. By having multiple paths, the source and destination may not be easily traced. Also, some of the Intermediate nodes may be mobile (e.g., rovers), airborne (e.g., drones) or satellite uplinked thus making the Mesh more robust.

A GPS or Inertial Navigation System (INS) that is onboard the Identifier typically generates the location information that is packaged into the Standard Data packet, Encrypted and awaits transmission during an opportune moment. The opportunity could be by virtue of getting range of an Intermediate node or having the desired power levels (after trickle charging) or absence of radio scan by an enemy. The Standard Data packet may include source, destination, payload, error detection/correction, encryption, time stamp, hop info etc. One of the key features of the Mesh is its ability to transmit information other than position coordinates as required by mission. For example, the Identifier node may include a standard interface that can connect to a variety of sensors/data generators. For instance, a medical prognostic device connected to the Transmitter Node may transmit the vitals of the personnel carrying it in addition to his coordinates. This can help the Pilot to prioritize the extraction in case of medivac situation. This additional information will be made available on the MFD's HSI as an extended label around the Locator Symbology. An algorithm running on the Display application may be configured to prioritize/optimize and guide the pilot with his next extraction/waypoint point. In some embodiments, this may be a separate overlay with filters that could be selected/deselected by the pilot.

The Mesh need not be strictly RF during the origin or intermediate hops. For instance, if the Object being located/tagged is underwater, acoustic data link can be used to bridge data till it reaches an RF transmission capable node. This will allow the SAR vehicles to be even more versatile to locate objects that have/are submerged.

The Mesh also helps to locate lost Identifier nodes by virtue of its ability take packets routed by store and forward mechanisms. The Mesh can be programmed to have different routing algorithms based on the mission. The Mesh being a MANET can adopt routing schemes such as Game Theory, Search Theory and Rendezvous Search to locate nodes that are selectively visible (to friendly SAR and not a foe).

The Intermediate Nodes play a key role adding versatility and robustness to the Mesh. The Intermediate Nodes can perform store and forward of standard data packets with intelligence. In embodiments, an Intermediate Node includes an RF unit, Routing intelligence/logic, one or more power sources (e.g., battery packs, generators, etc.) and may be stationary or mobile. The mobility of the Intermediate Nodes may be active or passive. The active nodes may have ability to propel to locations that aid communication. The mobility could be achieved on Land, Air, and Water or (near) Space. The passive nodes may be piggybacked on other carriers whose movements are not aimed to enhance the communication deterministically, but have a good probability to aid the Packet movement probabilistically. Some models of Intermediate nodes could be inexpensive, expendable and could be deployed over vast geographical areas. The more advanced versions could be sizeable and have Satellite uplink or long-range terrestrial data link capabilities. While the small form factor nodes can carry battery packs, the larger ones can have energy generation/harnessing capability by tapping solar or other sources.

The Receiver Nodes may be onboard the Aircraft, Watercraft, or the like. The reception and treatment differ based on the Mesh that provides the Data. In a survival radio-based Mesh, the survival radio's (e.g., AN/PRC-112's) receiver can have expanded capability to receive packet Data that arrive in hops. In a versatile radio-based Mesh, a versatile radio receiver receives Data Packets from RF links (other than AN/PRC-112) and passes it on to the Wireless Gateway. A special receiver may receive Data packet sourced from an entirely different mobile or stationary platform which then gets routed to the Aircraft via connected Aircraft concept or other standard data link (that are not part of the Mesh) and is passed to the Wireless Gateway. The Data packets received from survival radio (Mesh or directly) are fed to Flight Manager (FM) for computation. Data packet from Mesh/Infrastructure not involving Survival Radio are treated by the Wireless Gateway for computation. The computed values are then fed via Ethernet to Cockpit Display System for the MFD to display the symbol on HSI's compass rose.

The Augmented personnel locator system (APLS) may be configured to provide a Locator Flight Plan (LFP) as an Overlay feature. This can be another option in the choice of flight plans available for the Pilot, others being Flight Plan (FPLN) and Alternate Flight Plan (ALTFPLN). The LFP is created by FM working in tandem with the Flight Display Application (or any such equivalent application). The LFP presents a mission specific flight plan with additional information. The LFP has symbols depicting the Object tagged by Identifier node, the key parameters of the object (marked on a label), health/status of the data packets (staleness, hops, range, Signal to Noise ratio etc.). The FM generates an algorithmic suggestion for extraction of the Objects which is presented in the form of LFP on HSI. The Algorithm uses parameters of the Object such as proximity, health, difficulty, window of opportunity, mission needs, etc. The Objects appear as way points for the Pilots to Navigate. The textual and visual cues presented to Pilot in the Overlay can be customized/enabled/disabled using Bezel keys, Control Display Unit (CDU), Multi-Function Control Unit (MFCU) or any such HMI.

Features of the invention may include, but are not limited to, the following:

• • 1. Mesh networking of existing survival radios (e.g., AN/PRC-112) that will enhance range of PLS.
  • 2. A versatile radio-based Mesh network that can handle PLS Data from sources other than just the survival radio (e.g., AN/PRC-112).
  • 3. Pilots to be provided with more than just the positional Information of the Nodes.
  • 4. Algorithmic creation of new way points based on node's Data and hence a Locator Flight Plan.
  • 5. An exclusive overlay in Cockpit Display to assist Pilot in Locator based missions.
  • 6. While MIDS (Multifunctional Information Distribution Systems) and/or TTNT (Tactical Targeting Network Technology) could provide military tactical data, APLS deals with how data can be further used to assist the Pilots by Locator Flight Plan (LFP).

Additional features/improvements may include, but are not limited to, the following:

• • 1. PLS functionality is being implemented in CAAS based Displays for Rotor crafts. The proposed APLS could be provided as an enhanced version or stand-alone.
  • 2. Means of bringing in Data from variety of nodes using RF links and displaying them on Cockpit screen with information about them.
  • 3. This also provides a means of Integrating/connecting various players into a Mesh that can be connected with Cockpit Display.
  • 4. With Drone based missions being preferred more often due to the human liability involved in manned missions, the APLS could increase the safety of the Personnel in an inevitable manned mission.
  • 5. Gives a new dimension to Data centric battle field by connecting the players in the field, bringing in the data and presenting them on Cockpit Displays.
  • 6. Can lead to Ubiquitous Meshes that can be scaled on-the-go by using the versatility of the wireless interface.
  • 7. The Algorithmic way point and Locator Flight Plan creation could very well be used to create the Flight-plan-of-the-future. With more and more Data being made available, well informed decisions/directions could be taken/given by/to the Pilots.
  • 8. A move from Located Personnel to Connected Personnel with the Aircraft playing a central role.

The Physiological Sensor 102 is attached to Personnel body to tap appropriate parameters such as heart beat, blood pressure, body temperature etc. The GPS receiver 116 or other form of location/position sensor 116 (like inertial sensor) shall gather the location info of Personnel. The data is then fed to the controller 104 via the communication interface 110. The communication Interface takes the data and feeds to the processor which creates the standard (data) packets by adding other essential info such as source Identifier, packet identifier, destination address, error detection, error correction, encryption etc. The standard packets are stored in memory 108 in queue for transmission via the RF unit 112. The electronics are powered by the battery 114. The Identifier node is part of the Mesh 40 which is outside the Aircraft/Watercraft 50.

It may also have Physiological Sensor 202 and Location Identification sensor 216 (e.g., Global Positioning System or Inertial Navigation System) especially if it is also carried by personnel (who needs to be located as well). The RF unit 212 receives the incoming standard packet from an Identifier Node 100 or Intermediate Node 200 and sends it to controller 204 via communication interface 210. The processor 206 in controller 204 then routes the standard packet based on the destination address. The standard packet is stored in memory 208 and retransmitted via the RF unit 212. Squelch circuitry 218 may control the RF unit 212 during the switching process. The routing tables may be stored in the Memory 208 for static or dynamic routing.

The RF unit 312 receives the incoming standard packet which is fed to the controller 304 via the communication interface 310. The Controller 304 then processes the standard packet for outbound transmission based on destination address. Processing includes reading the destination address in the standard packet. Decryption may be done prior to reading. The standard packet is stored in memory 308 and retransmitted via the RF unit 312. Squelch circuitry 318 may control the RF unit 312 during the switching (between reception and transmission). The controller 304 may refer routing algorithms/tables resident in Memory 308 which is invoked by the software application running on the processor 306.

The standard packet is received by the RF receiver 402 and fed to the Controller 404 via the communication interface 410. The processor 406 in controller 404 processes the standard packet to accept or discard the same based on the correctness/completeness. Incomplete or mutilated packets may be reconstructed by algorithms. The standard packet is then scrubbed off other information (destination address, error detection, error correction, encryption etc.) into a short packet and is then fed to the Gateway 500 via the communication interface 410. The receiver 400 may be specific to the communication protocol they are designed to operate with or generic to work with multiple protocols. The Receiver 400 is onboard the Aircraft/Watercraft 50.
